The second concoction, the "Wake n' Bacon," features a fried egg on the maple-bacon crognet with American cheese and "Devil Sauce."

"It's a great taste in the mouth between the burger and the cheese and the sweetness of the maple sauce and the bacon," Katz said. "What can be bad about it other than you have to work out a little bit longer to eat more of them?"

The crognets will arrive fresh every morning to Devil Dawg's location on the DePaul campus, 2147 N Sheffield Ave.

Devil Dawgs will roll out the sandwiches Sept. 10.

Katz and his team of mostly DePaul students will cut the crognet in half and grill it.

"It's almost like a French toast where you have the crusty bits," Katz said.

Katz, who has been running the tiny walk-up burger and hot dog joint for four years, expects the items to be a hit with his college crowd, but also Chicago's foodie population.

Katz said he wasn't aware of any other restaurants in the U.S. that have coupled the crognet with a burger, but heard of a few in Canada.

"Everyone wanted fried Twinkies and fried this and fried pickles and fried Snickers bars and I said to myself, you’ve got a great doughnut craze that’s taking over the cupcake," Katz said.

Katz, who trained at New York's Culinary Institute of America, and has worked at the former Lincoln Park Blue Mesa, Wilde and Calucci's, said he loves the freedom his burger and dog joint has given him.

That freedom allowed for the crognet burger.

"Working in large kitchens under the pressure of executive chefs and everybody else, you are under the gun 24-seven," he said. "I wanted to take a step back and have some fun."
